る。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing lightweight cellular concrete panels. Specifically, when a lightweight cellular concrete slurry is poured into a molding mold having an irregular pattern on the inner surface of the mold, air bubbles remaining on the inner surface of the mold are removed, and a lightweight lightweight concrete panel having a good surface is obtained. The present invention relates to a method for producing a lightweight cellular concrete panel for obtaining.

納した構造である。[0003] By the way, many of the lightweight cellular concrete panels manufactured in this way have recently formed an uneven pattern on the panel surface in order to enhance the design. The configuration of the forming mold for that purpose is a structure in which an elastic pattern sheet having an uneven pattern formed on the surface is housed in the mold.

Then, after erecting the mold vertically, the mold is lowered to the horizontal state while holding the cured lightweight cellular concrete panel, and the mold is removed from the mold. A cellular concrete panel can be formed.

た空気泡は、脱型後にパネル表面に穴となって残るので
パネル表面に欠陥を生じさせる原因となっている。However, in the manufacturing method as described above, when a lightweight cellular concrete slurry is poured into a forming mold, air bubbles are entrained, and the air bubbles are generated on the surface of the pattern sheet. Curing and curing may occur while remaining in the resin. Then, the air bubbles remaining on the surface of the concavo-convex pattern remain as holes on the panel surface after demolding, which causes a defect on the panel surface.

強いことから、模様シートの凹凸模様表面に空気泡が残
留しやすく、欠陥が生じやすい原因となっている。In particular, there is a recent tendency that there is a strong demand for engraving a concave and convex pattern in order to give a sense of quality by shading, so that air bubbles are likely to remain on the concave and convex pattern surface of the pattern sheet, causing defects. It is a probable cause.
